+Tianma Micro-electronics TM070RVHG71 7.0" WXGA TFT LCD panel
+
+Required properties:
+- compatible: should be "tianma,tm070rvhg71
+- power-supply: single regulator to provide the supply voltage
+- backlight: phandle of the backlight device attached to the panel
+
+Required nodes:
+- port: LVDS port mapping to connect this display
+
+This panel needs single power supply voltage. Its backlight is conntrolled
+via PWM signal.
+
+Example:
+--------
+
+Example device-tree definition when connected to iMX6Q based board
+
+ panel: panel-lvds0 {
+ compatible = "tianma,tm070rvhg71";
+ backlight = <&backlight_lvds>;
+ power-supply = <®_lvds>;
+
+ port {
+ panel_in_lvds0: endpoint {
